FILLER FOR TEXTILE FABRICS.

No Drawing.

To all whom it may concern Be it known that I, FREDERICK W. MAC- KENZIE,a citizen of the United States, residing at Washington, in the Districtof Columbia, have invented new and useful Improvements in Fillers forTextile Fabrics, of which the following is a specification.

My present invention relates to improvements in the art of laundryingtextile fabrics, and it has for its object to provide an improved fillerwhich is of such a character that when the fabrics are treated therewithduring or at the end of the washing operation, such fabrics may passthrough an ordinary mangle or ironing machine without liability ofsticking to the roll and tearing, and the fabric after passing throughthe mangle will possess a finish and gloss of a grade superior tothatattainable heretofore in machine ironing, and, in fact, the results arebetter than ordinarily obtainable in ironing by hand.

The invention is particularly adapted for use in laundrying large piecesof textile fabrics such, for instance, as tablecloths, the ironing ofwhich has heretofore presented difliculties, especially when the ironingwas accomplished by a mangle, the fabric when impregnated with theordinary starch having a tendency to stick to the roll of the mangleandtear. According to the present invention, however, fabrics andparticularly large ones when treated with my improved filler are notonly capable of passing through the mangle without liability of stickingto the roll or tearing, but a highly superior finish and gloss isobtained.

My invention consists essentially in treating the fabric with a noveland improved filler, preparatory to the passage of the fabric throughthe mangle, and it will be understood that. the invention is not limitedto any particular laundrying process.

s an example of the improved filler, I may give the following :Prepare asolution of approximately three gallons of neutral liquid soap(preferably Ivory) of the strength of fourteen pounds of soap to thirtygallons of water. Prepare a paste or emulsion of one gallon of pure cornstarch which may be in the proportion of seven ounces of corn starch toa gallon of water. Mix the gallon of corn starch paste Specification ofLetters Patent.

or emulsion with the three gallons of neutral liquid soap solution so asto incorporate them thoroughly, and add to the mixture half an ounce ofliquid blue, the latter being preferably of the strength of one ounce ofthe powdered blue to one gallon of water. The blue is not absolutelynecessary, but I prefer to use it, especially in the laundrying of whitefabrics.

One quart of the solution as prepared above is added to the last wateror rinse water of the washing wheel containing the fabric or fabrics tobe treated, the washing wheel preferably containing not more than twentygallons of water at the time the solution is added. The washing wheelmay then be operated for a sufficient period, say, five minutes, duringwhich the preparation is thoroughly incorporated with the fabrics, theliquid is withdrawn from the wheel and the surplus liquid is extractedfrom the fabrics, as usual. The fabrics are then passed through themangle or ironing machine in the usual way, and practical use hasdemonstrated that there is no liability of the fabric sticking to theroll of the mangle'and tearing and, moreover, fabrics ironed in this waypossess a perfect gloss and finish which could not possibly be obtainedin theordinary ironing operation ,by a. mangle or machine, and suchgloss and finish is superior to the results ordinarily obtained by handironing.

I claim as my invention:

1. An improved filler adapted for use 1n ironing textile fabricscomprising a neutral soap and pure corn starch thoroughly mixed insubstantially the proportions of one part starch to three parts of soap.

2. An improved filler adapted for use in the laundrying of textilefabrics compr1sing an intimate mixture of neutral soap, pure corn starchand bluing in substantially the proportions of three parts of soap toone part of starch.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
